Hello, I want to solve the basic system single basis in my project, but I am having trouble with data entry. Can you help me ? I am getting a warning that the number of mods is insufficient in dynamic analysis. Some single foundations show negative ground safety warning. I modeled my curtains as sticks, but I can't define a single foundation underneath, so I always made a foundation. Can't we make it a singular basis? The distance between my columns next to the dilatation joint is too short and the single foundation gives a warning of insufficient cross-section. In the section where the dilatation joint is located, singular foundations give an error. What are the options I need to change in the analysis settings when I analyze with a single basis? I'm attaching the two projects I'm having problems with. I would be very happy if you would review my project and tell me what I lack. Good work.
